Stable ocular mounting assembly
First Claim
1. An improved ocular mounting assembly having a pair of ocular support arms slidably disposed within an assembly housing, each arm having an end for supporting a respective ocular, cross-sectional geometry of the support arms being such that an open space is created in the housing when the arms are extended, the improvement comprising:
- a pair of stabilizing structural members, one disposed inside each end of the assembly housing so as to occupy at least a portion of the open space left by the support arms inside a cross-section of the housing at the ends of the assembly housing, thereby stabilizing the support arms, when the support arms are extended from the ends of the assembly housing.

Abstract
An improved ocular mounting assembly having a pair of ocular support arms which can be extended by sliding out of a box-section assembly housing for supporting a pair of ocular devices attached to the ends of the support arms. The improvement is a pair of stabilizers disposed inside the assembly housing and providing stability against rotational motion when the arms are extended. In one embodiment, the stabilizers are interference-fitted balls, retained in position by retainer holes in the assembly housing, and receding into recess cut-outs at the end of the support arms when the arms are fully retracted. In an alternate embodiment, the stabilizers are L-shaped, and can be either an integral part of the housing or bonded to it with adhesive.

6. An improved ocular mounting assembly having a pair of ocular support arms slidably disposed within an assembly housing having a rectangular cross-section, each arm terminating in an end to which there is attached a respective ocular, the support arms having an outer boundary and an inner boundary, a portion of the outer boundary having a shape conforming with the rectangular shape of the cross-section of the housing, thereby creating an open space in the cross-section of the housing when the arms are fully extended, wherein the improvement comprises:
a pair of stabilizing structural members disposed inside each end of the assembly housing substantially occupying the space left by the support arms inside the cross-section of the housing at the ends of the assembly housing and providing an interlocking interface with the ends of the support arms at the ends of the assembly housing. - View Dependent Claims (7, 8, 9, 10, 11)
